To all whom it may concern: about seven-sixteenths of an inch in width at Be it known thatI, CHARLES E.

these vertical planes and are commonly each The scavenger-roll C is of any usual con- Q Ii struction, being preferably a wooden roll covered with cloth and provided with metallic pivots or arbors c, which serve as journals, there being a scavenger-roll between each roller-stand A and the next; but the body of each scavenger-roll is represented as long enough to reach from one stand to the next.

The scavenger-roll support D is represented as a spring of sheet metal bent to a semielliptic form and havinga slot d, through which the bolt E passes up into the under side of the head a said slot d being of sufficient length to permit the support D to be adjusted back and forth in the usual manner. In front of its semielliptical portion the spring D is narrowed at d sufficiently to admit of the part cl rising and falling freely in the slot a of the post a, through which slot said spring projects. The free end portion of the spring D is wider than the slot at (but not wide enough to project beyond the sides of the head a of the stand A) and is provided with a depression (Z which serves as a half journal-box for a scavenger-roll arbor c, and the spring being slit or divided longitudinally at (1 from its free end to near its point of attachment serves to support the adjacent ends of two scavenger-rolls, as shown in Fig. 2. The spring supports D hold the scavenger-rolls against the bottom of the front fluted roll.

I claim as my invention- 1. The combination of the roll-stand, havin g a head, drawing-rolls, supported therein, and a scavenger-roller support, secured to said head and lying wholly within the vertical planes of the side walls of said head.

2. The combination of the roll-stand, having a head and having a post provided with a vertical slot extending through said post from front to rear thereof, and a roller-support secured on said stand in the rear of said post and extending through said slot.

3. The combination of the roll-stand, having a head and having a post provided with a vertical slot extending through said post from front to rear thereof, a roller-support secured on said stand in the rear of said post and extending through said slot, and provided with a depression to form a bearing in front of said post and a roll, provided with a pivot or journal, supported in said depression.

4. A roller-supporting spring, havinga coinparatively-broad rear end and a split shank, and adapted to be attached to a roll-stand, provided with a head and with a post, having a vertical slot, extending through said post from front to rear thereof, said spring being adapted to be secured to said head in the rear of said post and to extend through said slot and to press against the under side of said head in front of said post.

In witness whereof I have signed this specification, in the presence of two attesting witnesses, this 8th day of April, A. D. 1898.

CHARLES E. LOVEJOY.
